UNITED STATES PATENT OFFICE.

JOSEPH R. MORRISON, OF KENNEWIOK, WASHINGTON.

MOTOR.

To all whom it may concern:

Be it known that I, J osErI-I R. MORRISON, a citizen of the UnitedStates, residing at Kennewick, in the county of Benton and State ofWashington, have invented new and useful Improvements in Motors, ofwhich the following is a specification.

This invention relates to a motor of the spiral or screw type adapted tobe actuated by a flowing fluid impinging upon the spiral or screw, themotor being placed in a water course, flume or natural stream of water.

The invention has for one or its objects to improve and simplify theconstruction and operation of devices of this character so as to becomparatively simple and inexpensive to manufacture, reliable andefficient in use, and composed of comparatively few parts.

Another object of the invention is the provision of a current motorincluding arotatable cylinder open from end to end and having a spiralor screw arranged therein for providing a plurality of impact surfaceswhereby the flow of water through the cylinder causes rotation of thelatter, the cylinder being mounted in a frame of novel construction, andadapted to rotate a shaft from which power can be taken for any suitablepurpose.

\Vith these objects in view and others, as will appear as thedescription proceeds, the invention comprises the various novel featuresof construction and arrangement of parts which will be more fullydescribed hereinafter and set forth with particularity in the claimsappended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention, Figure 1 is a plan view of the motor. Fig. 2 is a centrallongitudinal section thereof. Fig. 3 is a section on line 33, Fig. 1.Fig. 1 is a fragmentary side elevation showing the manner of connectingthe ice and drift protector with the frame of the motor.

Similar reference characters are employed to designate correspondingparts throughout the views.

Referring to the drawing, A designates the frame or body of the devicewhich may be of any suitable construction and size and provided with achamber 1 open from end to end for containing the rotatable element B ofthe motor. The element B consists of the cylinder 2 which is open atboth ends and provided with a spiral or screw of any desired pitch topresent a large impact area Specification of Letters Patent.

for causing rotation of the cylinder by .the The thrust on the cylinderis taken up by a plurality of bearings consisting of annularchannelshaped races 4 rigidly secured in the chamher. 1 of the frame andhaving a plurality of spaced rollers5 on which rides annular flanges 6formed externally on the cylinder, the flanges engaging in the races toprevent longitudinal movement of the cylinder in the frame A.

On the cylinder 2 are formed sprocket teeth 7 around which pass sprocketchains 8 which extend upwardly through openings 9 in the frame and passaround sprocket wheels 10 on the power-distributing shaft 11 supportedin bearings 12 on the top of the frame. Power can be taken from thisshaft in any suitable manner, as for instance, by a sprocket wheel 13capable of being clutched to the shaft 11 by engagement with a toothedcollar 14 on the shaft, the sprocket wheel 13 being clutched andunclutched by a lever 15 fulcrumed on the frame.

In order to prevent damage to the rotatable element of the motor by iceand drift material, a protector designated generally by C is arrangedover the inlet end of the frame. This protector may be constructed inthe form of a triangular frame having side horizontal slats 16 spacedapart to permit the water to pass between them and force the ice ordrift matter to the sides. On the corners of the frame are rods 17 fixedin bearings 18 and the protector is connected by eyes 19 which are sodesigned as to permit the protector to rise and fall with change in thewater level.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that Having thus described the invention, what A I claimis 1. A motor comprising a frame proyided with a chamber open at bothends, a cylinder mounted therein and provided with a spiral extendingfrom one end thereof. to the other, annular bearing flanges, annularchannelshaped bearings fixed in the chamber and into which the flangesextend, a shaft mount ed on the frame, and. driving connectionsbetweenthe cylinder and shaft.

2. A motor comprising a frame having a chamber open at both ends,vertical rods secured at the ends of the frames, an ice and driftprotector arranged over the end of the chamber into which water flows,means for attaching the protectorto' the rods at the inlet end of theframe for permitting the protector to rise and fallwith the changes inthe water level, a cylinder rotatably 'm'o-unte'd' in the chamber andopen at both ienels, a) spiralin'a the eyl inder and rigidly securedthereto, annular external flanges on thecylinder, channel-shaped annularbear- 'in-gs fixed on the frame and embracing the flanges, anti-friction devices arranged in the bearings, sprocket teeth extendingaround the cylinder, a driving shaft having a sprocket wheel, and asprocket chain passing around said teeth and wheel.

In testimony whereof I afiix my signature in presence of two witnesses.
